問17番なんですが、なぜ炭素間の二重結合じゃないと脱色できないんですか? 一応二重結合はあるのに🤔🤔

4問 次の問い (問1~5) に答えよ。 (配点 20 ) 問1 ちから一つ選べ。 16 カルボニル化合物に関する記述として語りを含むものを、次の日のう Fc=cf CH3-C ①アセチレンに触媒を用いて水を付加させると, ホルムアルデヒドが得ら れる。 アセトアルデヒドは, 工業的には触媒を用いてエチレンと酸素を反応さ せてつくられる。 ③ 2-プロパノールを酸化すると, アセトンが得られる。 アセトンにフェーリング液を加えて加熱しても, 変化はみられない。 ⑤ ホルムアルデヒドとアセトンは,いずれも水によく溶ける。 問2 分子式が C, Ho O の有機化合物Aがある。 この化合物Aを酸化したところ, 分子式がC,HOのカルボニル化合物 B になった。 化合物Bにヨウ素と水酸 化ナトリウム水溶液を加えて温めると, ヨードホルムの沈殿が生成した。 化 合物 A,B に関する記述として最も適当なものを、次の①~⑤のうちから一 つ選べ。 17 ① 化合物 Aは,第一級アルコールである。 ②化合物 A は,化合物Bと反応してエステルを生成する。 化合物 Aには,鏡像異性体が存在する。 ④ 化合物Bは、臭素水を脱色する性質がある。 CH3-C ⑤化合物 B には,シスートランス異性体 (幾何異性体)が存在する。 (第2回-14)
